I think it’s time that society started taking some steps back.
Yes back in our grandparents’ day people did stay in unhappy marriages, often where there was abuse, and in many instances that wasn’t ok.
But now we’ve gone to far the other way and marriage has become disposable, to the point that people start planning for divorce before they’ve even said “I do.”
Where’s the middle ground? Yes some marriages are abusive and nobody should be staying in an abusive relationship.
But equally many marriages are just stale, and people feel some kind of entitlement to go out chasing a new big shiny dream with 0 consideration for the children left in the middle.
Once you have children then yes. Those children come first. If that means you have to stay in a marriage where you’re not getting laid then so be it. The choice you made when having children was that they come first.
And I would take this further.
If people do leave relationships, then putting their children first means not moving on to someone else who you’re going to introduce into their lives.
We need to look back a bit too what really is best for the children. And part of that means that no, it’s not ok to have several children by several partners.
It’s not ok to bring new partners into their homes, with step and half siblings from several fucked up relationships.
If you move your children away from their other parent, then you owe it to those children to not move on with someone else, and yes. That includes not having more children.
